[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present utility model and its application or use. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0027] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for the sake of convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationship. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the description. In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, further discussion thereof in subsequent drawings is not required.

[0028] In the description of the present invention, it should be understood that the use of terms such as "first", "second", etc. to define components is only for the convenience of distinguishing the corresponding components. Without further statement, the above terms have no special meaning and thus should not be construed as limiting the scope of the present invention.

[0029] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "mounted", "connected", and "coupled" shall be construed in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a direct connection or an indirect connection through an intermediate medium.

The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.

[0031] There are many types of air conditioners, including household air conditioners, cabinet air conditioners, etc. Cabinet air conditioners refer to air conditioners used to cool equipment, which are usually placed in the cabins of equipment, such as in cabins like ship cabins and electrical cabins, and have higher requirements for high strength, high weight, etc.

[0032] As Figures 1 to 7 shown, the air conditioner of this embodiment includes a frame 1 and a refrigeration cycle component disposed within the frame 1. The refrigeration cycle component includes a compressor 45, a condenser 44, an expansion assembly 46, and an evaporator 41, corresponding to the compression process, condensation process, expansion process, and evaporation process of the refrigeration cycle.

[0033] The frame 1 includes a plurality of interconnected strip beams 10. As shown in the figure, the frame 1 includes a plurality of interconnected horizontally placed strip beams and vertically placed strip beams. The plurality of strip beams 10 include strip beams 10 with a C-shaped cross-section and / or strip beams 10 with an L-shaped cross-section. As Figure 7 shown in the embodiment, the inner surface or outer surface of the strip beam from which the lead is led out includes three sequentially connected surfaces, with a C-shaped cross-section, and it is a strip beam with a C-shaped cross-section. The strip beam 10 with an L-shaped cross-section refers to a strip beam whose inner surface or outer surface includes two connected surfaces, with an L-shaped cross-section. The strip beam 10 with a C-shaped cross-section or the strip beam 10 with an L-shaped cross-section is lighter than the existing strip beam with a closed annular cross-section while meeting the strength requirements, and can better meet the requirements of high strength and low weight.

[0034] For the air conditioner of this embodiment, by using the strip beam 10 with a C-shaped cross-section and / or the strip beam 10 with an L-shaped cross-section to connect and form the frame 1, it helps to improve the strength of the frame 1 and reduce the weight of the frame 1, thus contributing to the formation of an air conditioner with high strength and low weight.

[0035] In some embodiments, the frame includes a frame body, and the frame body is formed by welding a plurality of strip beams. The frame of this embodiment is formed by connecting a plurality of strip beams 10 together by welding to form an integral frame, which can further improve the strength, load-bearing capacity, and anti-vibration ability.

[0036] In some embodiments, the frame body is a cuboid frame body 11, and the cuboid frame body 11 is formed by welding 12 strip beams 10. As Figure 6 shown, the main structure of the frame 1 is a cuboid frame body 11, and the 12 strip beams 10 corresponding to the 12 edges of the cuboid form the cuboid frame body 11.

[0037] The frame body of this embodiment is a rectangular frame body formed by connecting 12 strip beams 10 together by welding, with a regular shape, high strength, compact structure, and convenient layout.

[0038] In some embodiments, asFigure 6 As shown, the frame further includes a diagonal beam 12 connecting adjacent strip beams of the rectangular frame body. The diagonal beam 12 and the two strip beams connected thereto enclose a triangular cavity. As shown in the figure, the diagonal beam is a strip structure. The two ends of the diagonal beam are connected to two mutually perpendicular strip beams by means such as welding and threaded parts. The diagonal beam and the two strip beams connected thereto form a triangular structure, enclosing a triangular cavity. The diagonal beam structure is simple and easy to install, and at the same time can effectively improve the stability and load-bearing capacity of the rectangular frame body.

[0039] In some embodiments, as Figures 1 to 3 shown, the air conditioner further includes an evaporative heat exchange air duct 3 provided in the frame 1. The refrigeration cycle components include an evaporator 41 provided in the evaporative heat exchange air duct 3 and a plurality of axial flow fans 42 provided below the evaporator 41. During operation, the plurality of axial flow fans 42 draw air flow from the external environment into the evaporative heat exchange air duct 3. The air flow entering the evaporative heat exchange air duct 3 exchanges heat with the evaporator 41 and then is discharged into the external environment to cool the external environment. The external environment is the environment to be cooled by the air conditioner. During operation, the axial flow fans 42 draw air flow from the environment into the evaporative heat exchange air duct. After the air flow enters the evaporative heat exchange air duct, it flows to the evaporator 41 for heat exchange, and the air flow flows out of the evaporative heat exchange air duct 3 into the external environment after heat exchange and cooling.

[0040] In this embodiment, by arranging a plurality of axial flow fans (two axial flow fans in the embodiment shown in the figure) below the evaporator, compared with the setting of using a centrifugal fan in the conventional technology, the occupied size can be smaller, the structure of the air conditioner can be made more compact, and the occupied space can be further reduced.

[0041] In some embodiments, the air conditioner further includes a water receiving tray 51 provided in the evaporative heat exchange air duct 3 for receiving the condensed water on the surface of the evaporator 41. The evaporator 41 is provided above the water receiving tray 51, and the axial flow fan 42 is located below the water receiving tray 51.

[0042] After the air flow enters the evaporative heat exchange air duct, it passes by the water receiving tray 51 or passes through the opening in the water receiving tray 51, and then flows to the evaporator for heat exchange. A small amount of the cooled air flow will form condensed water. The setting of the water receiving tray 51 can receive the condensed water and does not affect the air flow in the evaporative heat exchange air duct.

[0043] In some embodiments, the air conditioner includes two water receiving trays arranged vertically and offset in the height direction, and the projections of the two water receiving trays on the horizontal plane do not overlap. This setting can receive the condensed water of the evaporator with a larger area while not affecting the air flow, so that the air conditioner can still receive the condensed water of the evaporator well when it needs to be inclined in some special environments.

[0044] In some embodiments, asFigures 1 to 6 As shown, the air conditioner further includes a plurality of panels 2 provided on the frame 1, and the plurality of panels 2 are located on different sides of the frame 1. In the embodiment where the frame shown in the figure includes a cuboid-shaped frame body, the plurality of panels 2 are located on different surfaces of the cuboid-shaped frame body, that is, on different surfaces corresponding to the six surfaces of the cuboid. The refrigeration cycle components include a heat dissipation fan 43 and a condenser 44 provided in the frame 1 for dissipating heat from the refrigerant. The air conditioner further includes a heat dissipation air outlet 63, a first air inlet channel 61, and a second air inlet channel 62 provided on different panels 2. When the heat dissipation fan 43 operates, the heat dissipation fan 43 draws in airflows from the first air inlet channel 61 and the second air inlet channel 62 to cool the condenser 44, and then sends out the airflows that have cooled the condenser 44 from the heat dissipation air outlet 63. In the embodiment shown in the figure, the first air inlet channel 61 and the second air inlet channel 62 are respectively provided on the side surface and the bottom surface of the frame 1. Louvers are provided on the panel located on the side surface of the frame 1, and the airflow channel passing through the louvers forms the first air inlet channel 61. An air intake mesh hole is provided on the panel located on the bottom surface of the frame 1, and the airflow channel passing through the air intake mesh hole forms the second air inlet channel 62.

[0045] In this embodiment, by providing two air inlet channels, the air intake volume can be increased, and the heat dissipation effect of the heat dissipation fan on the condenser can be improved. At the same time, the first air inlet channel 61 and the second air inlet channel 62 are arranged on different panels. In special cases, such as when one panel is relatively close to the wall or blocked by foreign objects, the air resistance of the air inlet channel on this panel will be relatively large. At this time, the air inlet channel on another panel can still be used, and the reliability is higher.

[0046] In some embodiments, the heat dissipation fan 43 is located between the heat dissipation air outlet 63 and the condenser 44. The heat dissipation fan 43 further includes a wind blade and a rotating shaft for driving the wind blade to rotate. The condenser 44 and the heat dissipation air outlet 63 are located on the axis of the rotating shaft.

[0047] In this embodiment of the heat dissipation fan 43, both ends are respectively facing the heat dissipation air outlet 63 and the condenser 44 directly. The flow field of the airflows for dissipating heat from the condenser and discharging from the heat dissipation air outlet is better. The air outlet efficiency of the airflows discharged from the heat dissipation air outlet is high, and the heat exchange effect of the condenser is good.

[0048] In some embodiments, as Figure 5 shown, the heat dissipation fan 43 further includes an air outlet grille 431 surrounding the wind blade, and the air outlet grille 431 is provided in the heat dissipation air outlet 63.

[0049] In this embodiment, setting the air outlet grille can guide the air outlet of the heat dissipation fan, further improve the air outlet efficiency, and improve the heat dissipation effect of the condenser. At the same time, the heat dissipation fan is arranged closely to the panel. After the panel is removed, the heat dissipation fan can be overhauled, and the overhaul is convenient.

[0050] ​In some embodiments, the air conditioner further includes an evaporative heat exchange air duct 3 disposed within the frame 1. The refrigeration cycle components include an evaporator 41 disposed within the evaporative heat exchange air duct 3 and a plurality of axial fans 42 disposed below the evaporator 41. During operation, the plurality of axial fans 42 draw in the air flow in the external environment into the evaporative heat exchange air duct 3. The air flow entering the evaporative heat exchange air duct 3 exchanges heat with the evaporator 41 and then is discharged into the external environment to cool the external environment. The air conditioner further includes a partition plate 52 disposed within the frame 1. The partition plate 52 is located between the evaporative heat exchange air duct 3 and the condenser 44. The partition plate 52 is used to isolate the air flow within the evaporative heat exchange air duct 3 from the air flow between the heat dissipation fan 43 and the condenser 44.

[0051] In this embodiment, the partition plate 52 is provided to separate the air flow of the evaporative heat exchange air duct and the air flow when the heat dissipation fan dissipates heat from the condenser, so that the air flow field for the condenser to dissipate heat and the air flow field for the evaporator to exchange heat do not affect each other. At the same time, the partition plate 52 is detachably disposed on the frame, and by removing the partition plate 52, it is convenient to repair components such as the evaporator and the axial fans.

[0052] In some embodiments, as Figure 3 shown, the air conditioner further includes an electrical box 7 disposed between the condenser 44 and the partition plate 52. The air flow entering the frame 1 from the first air inlet channel 61 and the second air inlet channel 62 flows over the surface of the electrical box 7. As Figure 3 shown in the embodiment, the electrical box 7 is arranged above the frame 1. The top panel of the frame can be directly removed to repair the electrical box 7. Through the above compact structural layout design, both the space utilization rate can be improved and the maintenance and control can be made convenient. The sheet metal seams of the electrical box 7 are treated with full welding, and the incoming and outgoing wires of the electrical box 7 are locked and sealed with electrical connectors with an IP68 protection level. A waterproof sealing material is pasted between the electrical box cover of the electrical box 7 and the electrical box, and the entire electrical box 7 forms a completely enclosed space, effectively preventing water vapor from entering, and having high reliability.

[0053] The electrical box 7 in this embodiment can be cooled by the air flow drawn in by the heat dissipation fan, which helps to cool the electrical box and improve the stability and reliability of its operation.

[0054] In some embodiments, the frame 1 and the box body of the electrical box 7 are made of stainless steel, and the partition plate 52 is made of aluminum alloy.

[0055] In this embodiment, for the main load-bearing components such as the frame 1, the box body of the electrical box 7, and the water receiving tray, stainless steel is used, and for the components with less force such as the partition plate, aluminum alloy is used, so that while ensuring high strength, light weight can be achieved.

[0056] In some embodiments, the condenser 44 includes a microchannel heat exchanger 441 made of aluminum.

[0057] The condenser 44 in this embodiment uses a microchannel heat exchanger 441 made of aluminum, which has a higher heat exchange capacity than the conventional finned copper tube heat exchanger under the same volume, can achieve a smaller volume, save space and reduce weight.

[0058] In some embodiments, the refrigeration cycle component further includes an expansion assembly 46 for expanding the refrigerant output by the condenser 44. The expansion assembly 46 includes a capillary tube.

[0059] The expansion assembly 46 in this embodiment uses a capillary tube, which is more reliable, has a lower cost and a lighter weight than expansion assemblies such as electronic expansion valves.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that it is still possible to modify the specific implementation manners of the present invention or perform equivalent replacements for some technical features; without departing from the spirit of the technical solutions of the present invention, they should all be covered by the scope of the technical solutions claimed by the present invention.
